In order to solve the technical problems, the technical scheme provided by the utility model is as follows: a novel door hinge connecting device comprises a hinge base, wherein the front surface of the hinge base is sequentially provided with a first hinge lug and a second hinge lug from top to bottom, the first hinge lug and the second hinge lug are both provided with mounting holes, a rotating shaft is arranged between the first hinge lug and the second hinge lug and penetrates through the mounting holes, the two ends of the rotating shaft respectively extending out of the first hinge lug and the second hinge lug are respectively provided with a limiting block, a door leaf hinge, a plane bearing, a base plate and a retainer are sequentially arranged on the rotating shaft and positioned between the first hinge lug and the second hinge lug from top to bottom, a bearing is arranged between the door leaf hinge and the rotating shaft, the plane bearing is respectively in close contact with the adjacent door leaf hinge and the backing plate, at least eight through holes are uniformly distributed on the retainer about the axis of the rotating shaft, ball balls are arranged in the through holes, four linear rolling grooves I for accommodating rolling of the ball balls are arranged below the base plate, and four linear rolling grooves II for accommodating rolling of the ball balls are arranged above the hinge lugs II.

Furthermore, waist-shaped holes are formed in the four corners of the front face of the hinged support.

Furthermore, holes for the rotating shaft to pass through are waist-shaped holes in the base plate and the retainer.

Compared with the prior art, the utility model has the advantages that: the ball is added between the base plate, the retainer and the hinge lug II, so that when the door leaf is closed, the weight of the door leaf is transferred to the ball from the hinge lug, and the ball can stably support the door leaf and is convenient for the door leaf to move, so that after the product is used, the heavyweight door leaf is very flexible to open and close, the door leaf is light and quick to move, and the door leaf is durable and has prolonged service life.
